If you have a JSON document, there are several ways you could go about getting it into SQL Server.
If it’s a small document, you could copy and paste its contents. If it’s a larger document (or even a small one), you might want to import the whole file.
This article presents an example of importing a JSON file into a SQL Server database.

OPENJSON() is a table-valued function that returns JSON in tabular format. That is, it converts your JSON into a tabular result set consisting of rows and columns. Therefore, it enables you to insert it into a table.
In SQL Server, you can use the SET STATISTICS TIME statement to display the time it takes to execute a T-SQL statement.
More specifically, it returns the number of milliseconds required to parse, compile, and execute each statement.
When SET STATISTICS TIME is ON, the time statistics for a statement are displayed. When OFF, the time statistics are not displayed.
The setting of SET STATISTICS TIME is set at execute or run time and not at parse time.
SQL Server error message 113 occurs when you omit a closing comment mark.
This can occur when you open a comment but forget to close it. It can also occur when you accidentally type an opening comment.
There may also be odd occasions where you get this error due to other factors, such as the way your SQL utility handles certain keywords etc.

If you’re using JSON_VALUE() to return values consisting of a long string, you might find that it returns NULL instead of the actual value.
Or, you might be getting an error.
Continue readingIn SQL Server, you can use the SET STATISTICS PROFILE statement to display the profile information for a T-SQL statement.
STATISTICS PROFILE works for ad hoc queries, views, and stored procedures.
When STATISTICS PROFILE is set to ON, each executed query returns its regular result set, followed by an additional result set that shows a profile of the query execution.
In SQL Server, you can use the SET STATISTICS IO statement to generate detailed information about the amount of disk activity generated by a T-SQL statement.
In graphical tools like SSMS and Azure Data Studio, you can view this information in the Messages tab.

Continue readingIf you’re trying to extract values from a JSON document, but one or more of the values on the same level have duplicate keys, you might run into problems if you try to extract those values using JSON_QUERY() or JSON_VALUE().
Both of those functions will only return the first value that matches the path.
Fortunately, there’s another option.
The OPENJSON() function will return all values from any duplicate keys on the same level.
